#### Lithium Ion battery cells might be on the electric motor propulsion rise, supplanting Nickel Cadmium. However, 6 cell 12V lead acid batteries still provides the critical voltage to fire up the internal combustion ignition and run accessories for 99% of the world's passenger vehicles, including those pesky petrol electric hybrids.

#### Extreme conditions take their toll on lead acid battery performance:

- **TIME** \- After 5 years typical passenger automotive use results in corrosion of the lead cathode plates, reducing the ability to hold charge current
- **HEAT** \- Ditto the effect of TIME (above)
- **COLD** \- Electrolyte passes current more slowly, while reduced engine lubrosity demands more electric current to crank
- **SHORT TRIPS** \- Sulfuric acid needed for cathode process stratifies at bottom of battery leaving upper lead plates only with water solution.

#### The recurrence of these extremes over time may necessitate a battery jump to start the 12V battery starting motor vehicle. The traditional go-to is an available and willing running donor car with a pair of long jumper cables is one resource. When there is no running donor vehicle available, a portable jumper is the next best bet.

#### Automotive accessory distributor 70mai supplied Roadblazing.com editors with their latest portable car jumper, the [70mai Jump Starter](https://70mai.store/products/ps01-jump-starter?ref=roadblazing.com) by Xiaomi Youpin.
